54 ACIDALIA. By L. B. Prout. 



lactea. A. lactea Btlr. (3g, (J$). Whitish ochreous, sometimes more tinged with fleshcolour; a more or less 



strong dusting of fine fuscous atoms. The ^, as the figures show, is slightly less narrow- winged than the $ 

 and more weakly marked, a reddish-brown or fuscous common oblique band which is present in the latter, 

 and often very strongly expressed, being weak or almost entirely wanting in the former. In both sexes the discal 

 dots are very distinct and black and there is an outer series of black dots, sometimes connected by a very 

 fine line, its course slightly oblique and curved on the forewing, parallel with the distal margin on hindwing. 

 In addition, the forewing often bears an indistinct inner line and the hindwing a second series of dots, or a 

 dark shade, indicating the proximal shading of an obsolescent pale subterminal line. Under surface more 

 weakly marked, the cell-spots remaining distinct. Common in Japan and some localities in N. E. China, and 

 possibly has a much wider range, as it is by no means certain that it is any thing more than a form of the 

 Indian defamataria Walk., which, however, seems to have the distal margin of the forewing slightly more 

 oblique and that of the hindwing even straighter. Hampson has sunk lactea to emissaria Walk., which was des- 

 cribed from a tinr $ from Moulmein and may possibly be a dwarfed form of the same species. This can only 

 be decided when further material from Burma is available for study. There is probably a succession of broods 

 throughout the summer; Leech obtained it at Fu-chau and Ningpo in April, Wileman in Japan in August 

 and again at the end of September. My friend Dr. M. Culpin took it in the neighbourhood of Shanghai on 

 the 13 August and agam commonly frcm the 20 September. He obtained eggs on the last-mentioned date, 

 and reared moths indoors about the middle of November. The larva, like those of most Acidalia, is extremely 

 long and thin, not or scarcely rugose, the subsegmentation conspicuous, the subsegments very numerous; colour 

 brownish, with darker dorsal band, spiracles dark and conspicuous. The moth h attracted by light. 



dotiovani. A. donovatii Dist. (= extraordinaria Stgr. = extremata Wair.) (3 g, as extraordinaria) is also possibly 



nothing more than a very much larger form of defamataria Walk. Like typical defamataria from Ceylon, the wings 

 are of a slightly more extreme shape than in lactea, and have a rather more strongly dark-dusted under surface. 

 The sexes are apparently nearly alike, but I can only judge from two males; for some unexplained reason, the 

 $ is the more generally taken. South Africa, Cameroons, Nigeria, Syria; may be expected also from some in- 

 tervening localities. The dated specimens known to me were taken in August, November and December (S. 

 Africa) and 27 April (S. Nigeria). I can find no appreciable difference between the African examples and the 

 Syrian. On the latter Staudinger, apparently unacquainted with Butler's Lycauges, founded a new genus 

 Longula. His publication of genus and species dates from the end of June 1892, Distant's description under 

 the name of donovani from April of the same year. 



andresi. A. andresi Draudt, only recently described, is at present luiknown to me, but the description is good 



and leaves no doubt that the species is referable to this section. The arrangement of the markings is compared 

 with the ochroleucata-growp , but the wings are much narrower with sharper apex. 16 — 17 mm. Hindwing 

 not angled. Scaling dense and smooth. Yellow-grey, strongly dusted wdth black scales, towards the distal 

 margin (especially on the hindwing) with a violet-reddish hue. Discal dot distinct on both wings. Forewing 

 with three moderately oblique, distinctly dentate lines, which are slaty black in the 5, more purplish or reddish 

 in (^. The dark shading of the subterminal is distinct, running to the apex, between the 3. radial and 2. me- 

 dian forming distally projecting spots, on the 2. submedian thickened into a large, conspicuous spot. Distal 

 marginal line black, interrupted at the veins, here accompanied on each side (i. e. on the wing and the fringe) 

 by black spots. Hindwing with the inner line wanting, otherwise similar. (^ antenna with the joints project- 

 ing very strongly and with long, strong tufts of ciUa. The types, a (J and a $, are in the collection of Herr 

 Andres, Bacos, and were bred on the 14 October and 19 October from larvae fomid on Conyza at Cherbine, 

 Lower Egypt. I know of no other examples. Larva not described. 



steganioides-group. 



Palpus short, smooth. (J antenna with slender, strongly ciliated pectinations. Cells rather short. Hind- 

 wing with second t-ubcostal shortly stalked or nearly connate with first radial (gen. div. ?). 



steganioides. A. stegatlioides Btlr. (4 m). Reddish grey, paler and less red from the base to the median line and in 



apical half of distal area. Forewing with costal edge narrowly darkened ; first line angled outwards on the folds ; 

 median line almost straight, from middle of costal margin to middle of posterior margin, preceded by dark 

 discal spot and followed by a slight dark shade; outer line sinuous and dentate, rather near the margin, es- 

 pecially between the third radial and second median, where it is followed by some dark suffusion ; a dark termi- 

 nal line; fringe long, its proximal half dark, enclosing pale spots opposite the veins. Hind\ving without inner 

 line and discal spot, the outer line indistinct, further from distal margin than on forewing. Underside paler, 

 not or scarcely reddish, the markings weak, but both wings with distinct dark discal spot. Common in Japan,
